CLOTHES-DRYING MACHINE.

Application filed August 27, 1926.

This invention relates to a drier that may be advantageously used for drying rags, wearing apparel and various kinds of cloths', particularlyy in establishments where large quanti ties of various kinds of material are washed or otherwise treated and must be dried.

Uur invention particularly relates to that type of drier wherein cloth passes through a rotary foraminons cylinder or receptacle subjected to heated air, and in connection with this type of machine we have made certain improvements that may be characterized as follows:

First, there is a pivoted adjustable cradle for supporting a rotary foraminous receptacle and it is by virtue of this cradle that the receptacle may be placed at a desired inclination to regulate the passage of cloth through the receptacle.

Second, there iscombined closure and feeding devices for the ends of the foraminous receptacle so that Icloths may be fedinto and outof the ends of the receptacle with the ends of the receptacle slit to prevent the loss of heated air used for drying cloths in the receptacle. Y

Third, there is a novel housing and arrangement of flues by which an air heating apparatus may `supply air to a chamber containing the rotary receptacle in which cloths are subjected tothe .drying action of the. heated air.

The above are leading features of our invention and details of construction will appear as Athe invention is described in connection with the drawings, wherein Figure 1 is a vertical longitudinal sectional View of the drier; Y

F ig. 2is a vertical cross sectional View of the-same, and

forami nous receptacle.

In the drawings, the reference numerals 1 denote the substantial side frames affording bearings for a transverse shaft 2 and loose on this shaft are sidearms 3 supporting the lower end of a substantially7 semi-cylindrical cradle orrsupporting frame 4t. The opposite end of the cradle L1 has supporting arms 5 loosely mounted on a transverse shaft 6, onrnaled in bearings 7, carried by the upper ends of adjustable uprights 8. These adjustable uprights and the frames 1 are supported from the base or floor 9 of a substantially oblong lionsin having end walls 10 and 11, side walls 12 and 13, and a substantially pyramidically shaped top wall 111. This housing will be Serial No. 131,842.

rights, and thus adjust the outer end of the.-

cradle relative to its pivoted end.

The cradle or supporting frame 1 has a pair of transverse members 1S at each end thereof and these members support rollers 19 on which revolves a foraminous inclined receptacle. The receptacle comprises end sleeves 20 and 21 connected by a plurality of longitudinally disposed equally spaced T bars 22 and these bars are connected by equally spaced rings 23 supporting a foraminons cyl inder 24 which has its ends suitably attached to the end sleeves 2O and 21. The cylinder 24 is preferably made of non-corrodible interwoven wire so that air may readily enter the cylinder in whichthe cloths or material to be dried is placed and tumbled about by the bars 22 providing longitudinal ribs on the interior of thecylinder. Since the cylinder is inclined the cloths or material may be tumbled about from the upper receiving end of the cylinder to the lower discharge end thereof and during passage through the lcylinder be subjected to a blast of warm air, as will hereinafter appear.

On the end sleeves 20 and 21 are circumferential rails or bearing rings 25 that engage the rollers 19 and adjacent said rails are circumferential racks o r gears 26 meshing with pinions 27 mounted on a longitudinal' shaft 28 at one side of the cylinder. This shaft is journaled in a bearing 29 carried by one of Figz isa plan of the recelving end of the' the arms 3 of the cradle 1 and the opposite end of the shaft is onrnaled in a bearing 30 carried by an arm 31 co-extensive of one of the cradle arms 5. On the shaft 28 is a worm 32 meshing with a worm wheel 33 mounted on the shaft 2.

The end sleeve 21' of the foraminous receptacle extends into the flanged end of a discharge casing 34 through which extends the shaftY 2, said discharge casing being loosely mounted in an opening 35 provided therefor in the end wall 11, so that cloths or other material may be discharged from the casing through a chute 36 forming part of said casing.V The casing may shift in the opening 35 whenv the receiving end of the cylinder V24 is raised or lowered and because this casing is movable we prefer to mount an electriemotor 37 on the' casing for driving the shaft 28 by suitable power transmission elements generally designated 38. The

motor driven shaft 28 will cause the cylinder 24 to be revolved in the cradle relative to the flanged end of the discharge casing 34 and this relative movement may be oscillatory or in first one direction and then in the other, if so desired, by providing'a reversible motor or reversing power transmission devices.

The vend sleeve Q() extends into the flanged end of a casing 39- having a receiving chute` 40. The casing 39 is supported from the shaft G, extends into an'opcning 41 ofthe end'wall 10` and is connected to the end wall 10 by a flexible member 42 serving as a closure for the opening 41, yetpermitting adjustment of the receiving casing 3i) in the opening 41.

On the shafts Q'and G within the casings 34 "and 39 respectively are bladed feeding members 43 which also serve closures for thecasings toprevcnt'ran excess amount of heated airfrom escapingthrough said casings.' The bladed members 43 facilitate placing cloths orf'ma'terial inthe receiving endy of'the cylinder 24 and discharging the same through the casing 34,

Theshaft 6 lof vthecasing 39 has an end thereof 'provided with-a worm wheel 44 meshing with a worm`=45 on the shaft 2S and as-'this shaft is driven the bladed feed members 43 will be revolved in timed relation to the rotation of the cylinder Q4. These driven parts are operated so that cloths or material may be-continuously fed intoand out of the machine and dried during passage through the 'rotary lforalninous cylinder 24.

Again considering the: housing of lthe engine it yis preferable to insulate all of the` walls because of an air heatingv apparatus located above the base `or floor V9 of the-housing.` Suitable racks. 46 are provided for air heatingicoils 47 disposed in parallelism and longitudinally of the housing with suitable connections 48 through the end wall 11, so that hot iwater, steamy or any other heating agent may be circulated through the heating.

Heated air iiows upwardly, as indicated-'by arrows in Fig. 2, into ka flue 53 which communicates `with the top wall 14- ofthe housing. The flue 53 has an enlargement 54 for a rotary fanV 55 driven byv a flexible telescopic shaft 5Gfrom the electric motor 37. The fan 55 withdraws the air from the` lower part of the housing and delivers'it somewhat in the form of a blast over the foraminous cylinder E24, so that the air may enter the cylinder and circulate aboutit in the chamber 50.

1n the chamber 5() and supported from the sidewall l2 is a cin'ved air deflector 57 which cooperates with the partition 45 iniconlinin g the heated. air about the cylinder 24. The deflcctor 57 also cooperates with the partition 49 in forming an exhaust flue or channel 58 communicating with an outlet pipe 59"'carricd by the wall 12.`

From the foregoing it will be observed that air is drawn into the machine housing, heated and positively driven intoV and about the foi'amincms receptacle. Since cloths or material are being tumbled aboutl by the rotary or oscillatory motion of the receptacle and slowly fed through the receptacle it is obvious that the cloths or material will be dried. he machine iscapable-of general usefor drying purposes, and lwe would have it understood that: the structuralelements are susceptible to such variations and modifications as fall within` the scope of the appended claims;
